Hey, you are out and about travelling the world; why not share your experiences. Let people know what you have been up to, the places you visited, experiences, share your travel photos and let others know your thoughts on the places you have been to. You might think that you are not much of a writer but that doesn't matter so much as being able to passionately tell an account of your time in places you have stayed in or gone through.
What people are looking for are real tales from travellers who have visited places they have been or are thinking of going to and if you are like me than you just enjoy reading about others journeys.
Don't worry if you have never created a blog before it is very easy to do and there is lots of information on the internet to help and guide you through the steps.
The first thing you need to do is to sign up for a blog with a blogging service such as Live Journal or Blogger. Than register your blog with Google Adsense , they than place advertisements relevant to your blog. Every time someone clicks on one of the advertisements presto, you have just earned some money from Google. It is that easy!
While you're at it, why not start some other blogs about things you know about. It shouldn't just be restricted to your travels. The more blogs you have going, the more money you can generate and the longer you can keep travelling and stay away from that confining 9-5 office job!
One way to encourage traffic to your blog is to post it on forums that are relevant to your subject matter and to leave a comment on other people's blogs.
